MenACWY-CRM197 · 3 trials · 4 indications
To compare the percentages of subjects who reported at least one severe systemic reaction after any vaccination of MenACWY-CRM197 (detailed) plus routine vaccines (detailed) group to that observed in the routine vaccines alone (detailed) group administered at 2, 4, 6, and 12 months of age. Detailed - infants who provided reactogenicity and all Adverse Events (AEs) for 7 days, Serious Adverse Events (SAEs) and medically attended AEs.
Immunogenicity of one dose of MenACWY-CRM197 vaccine to one dose of MenC vaccine one month post vaccination was measured using serum bactericidal assay with human complement (hSBA) titer ≥ 1:8 against N.meningitidis serogroup C.
Percentages of subjects with human Serum Bactericidal Assay (hSBA) ≥1:8 as measured by serum bactericidal activity at 40 months and 60 months of age and associated 95% Clopper-Pearson CIs were computed for each of the serogroups within each of the vaccinated groups and in age-matched control subjects.

MenACWY-CRM197 is an investigational vaccine being developed for the prevention of meningococcal disease, including meningitis and meningococcal meningitis. It is designed to protect against meningococcal serogroups A, C, W, and Y. The vaccine is currently in clinical development and has not been approved by regulatory authorities.
MenACWY-CRM197 is being developed by Novartis AG, a multinational pharmaceutical company traded on the New York Stock Exchange under the ticker symbol NVS. Novartis is conducting clinical trials to evaluate the vaccine's safety and immunogenicity in various pediatric populations.
MenACWY-CRM197 is in Phase 3 clinical development. Clinical trials have been completed, including a large Phase 3 study with 7,744 participants evaluating the vaccine when administered with routine infant vaccinations. The vaccine remains investigational and is not yet approved for public use.
MenACWY-CRM197 has been studied in several completed clinical trials. NCT00806195 evaluated safety when given with routine infant vaccinations in 7,744 infants. NCT00667602 assessed safety and immunogenicity in 662 infants and toddlers. NCT00601731 evaluated immune response in 382 children aged 40 and 60 months.
MenACWY-CRM197 is a conjugate vaccine that combines meningococcal polysaccharides from serogroups A, C, W, and Y with the CRM197 carrier protein. This conjugation enhances the immune response, particularly in young children, by promoting T-cell-dependent immunity and immunological memory against meningococcal disease.
